Gränssnittskort Exsys EX-44140-2 PCIe

The Exsys EX-44140-2 PCIe is a multi I/O interface card that provides one parallel and two RS-232 serial ports using MosChip chipset components and two 16C550 FIFO UARTs. Designed for PCI-Express slots, the card delivers reliable wired connectivity for industrial and commercial PC systems and includes WHQL certification for driver compatibility on supported Windows platforms.

Advantages

The EX-44140-2 offers stable serial communications through dedicated FIFO UARTs, low-latency data transfer over PCIe, and broad device compatibility thanks to the MosChip chipset and WHQL-certified drivers. Its compact design fits standard PCIe slots and supports integration into existing PC setups without extensive configuration.

Suitable for

• Connecting serial RS-232 peripherals such as modems, barcode scanners, and industrial controllers
• Adding a parallel port for legacy printers or parallel-interface equipment
• System upgrades in industrial PCs, point-of-sale systems, and automation controllers

How to use

Install the EX-44140-2 into an available PCIe slot on a powered-off PC, secure the card to the chassis, and reconnect power. Boot the system and install the appropriate drivers provided by the manufacturer or via the operating system if available. Connect serial RS-232 devices using standard DB9 serial cables and connect parallel devices to the parallel connector. Configure port settings (baud rate, parity, stop bits) in the operating system or application as required.

Recommendations

Use shielded serial cables for longer runs to reduce interference, verify COM port assignments after driver installation, and consult device manuals for correct serial settings to ensure reliable communications.
